To all whom t may concern.' Y

Be it known that I, ISAAC IC. VSExToiN, a

" citizen of the'United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Riveted Receptacles, of which the followingis a specification.

This invention relates to a receptacle'such asan ash or: garbage barrel, comprising a sheet metal body usually cylindrical, rings or hoops forming the opposite ends of the receptacle and seated on the internal surface of the body, said hoops being usually formed from relatively thick rolled metal strips bent into annular' form, and longitudinal reinforcing strips of corrugated sheet metal seated on the external surface of the body and extending from end to end thereof. The hoops, body, and reinforcing strips are `connected by rivets at opposite end portions of the receptacle, each' rivet having a previ- .ouslyformed, head at one end and being upset at its opposite end after insertion in the partsabove mentioned, to form opposite heads which are necessarily relatively small. Heretofore'the larger rivet heads havebeen seated on the inner surfaces ofthe hoops,

these surfaces being exposed within the re ceptacle, and their opposite ends have been upset to form relatively small heads at the.

ciently large only by supplementing themwith burs or washers, placed upon the rivet Shanks before the upsetting operation and confined by the upset ends or smaller heads of the rivets against the outer surfaces of the reinforcing strips. Unless considerable care is taken in upsetting the rivets, the smaller heads fail to properly hold the washers, which are therefore liable to be knocked off.

My invention has for its object to elimi nate the burs or Washers, and the expense and lack of strength incidental thereto, to utilize the previously formed larger heads, which are condensed and hardened by the usual operation of forming headed rivets, as the external heads which are exposed to wear and rough usage at the exterior of the receptacle, and to utilize the relatively thick and rigid hoops as anvils on which the smaller heads are formed and by which said smaller heads are prcteetsd. l attain this object by 'seating the previously formed compacted and hardened larger rivet headsr on the external surfaces of the reinforcing strips, and upsetting the opposite lends'of the rivets on the inner surfaces of the hoops,

thusforming the smaller heads whiclnwliile` relatively small, areadequate, without VtheY burs or washers, because they are within the rigid hoops and are protected by vsaid hoops which compensate for the small size of the said heads.

Of the accompanying drawings forming a part ofY this specification,-`

Figure lisa side view of an ash barrelY one of the hoops, and a portion ofoneof theV reinforcing strips.

The same reference characters indicate the samejparts in all of the figures.

In the drawings, 12 represents the Vsheet metal body, and 13, 13 represent thev hoops which are seated on the internal surface of.

the body at opposite ends thereof, the hoops projecting from the endsof the body and having shoulders 14 bearing on said ends. One of the hoopsl constitutes the open mouth of the receptacle, and the other constitutes a support for lthe Vreceptacle -bottom 17.

The longitudinally corrugated sheet metal reinforcing strips 15 extend substantially from end to end of the body and are seated on the external surface thereof.

The body, hoops, and reinforcing strips are connected by rivets, each composed originally of a head 18 and a shank 19, as shown by Fig. 4, the head being hardened and condensed by the usual operations employed in making the rivet, and the shank being malleable.

In carrying out my invention, I insert the Shanks 19 in coinciding holes 21 fo-rmed for their reception in the parts to be connected, the Shanks being introduced from the outer sides of the reinforcing strips, and the heads 18 being seated on said outer sides. The inner ends of the Shanks 19 are then upset to form smaller heads 20 integral with Shanks, and seated en the inner surfaces of the hoops 13. Owing to the fact that the smaller heads 20 are within the rigid hoops, and are protected thereby against rough usage, they may be formed quickly and by a minimum displacement of the metal, and still possess adequate strength to prevent the withdrawal of the rivets, no enlargement by separately formed burs or washers being required. The previously formed and hardened heads located on the exterior of the receptacle are adapted to withstand any rough usage to which the receptacle may be subj ected.

The portions of the hoops on which the smaller heads are seated, constitute rigid anvils on which said heads are formed without liability of indenting the anvil surfaces, so that the smaller heads are formed more perfectly than would be the case if they were upset on the thin flexible reinforcing strips 15. The rivet holes 21 are preferably of considerably greater diameter than the rivet Shanks as shown by Fig. 5, so that the latter may be dropped freely into the holes when the barrel is presented in an approximately horizontal position to a riveting machine.

In practice I support the barrel horizontally over an anvil formed to occupy a portion of the space bounded by either hoop 13, the holes for one rivet being over the anvil, drop a rivet into the holes, and then compress the rivet longitudinally by a ram or hammer which descends on the larger rivet head, the pressure thus exerted upsetting the inner and lower end of the shank, to form the smaller head, and increasing the diameter of the remaining portion of the shank between the two heads, until it tightly fits the rivet holes. The barrel is then turned without removing it from the anvil, to locate other rivet holes over the anvil, and the operation is repeated.

The thickness and rigidity of the rings 13 prevent liability of cracking the rings by the enlargement of the diameter of the rivet Shanks.

It will be seen that the structure of the barrel is such that the parts consisting of the reinforcing strips, the body, and the hoops, areA adapted to be quickly and securely united by the rivets without the use of washers or burs.

The speed of the riveting operati on is inaterially increased by `forn'iing the rivet holes 21 so that the rivet shanks enter them loosely, and increasing the diameter of the Shanks by the operation which forms the smaller heads. Y

The reinforcing strips 15 are preferably secured to the body 12, prior to the abovedescribed riveting operation, by smaller rivets 25 1), which keep the end rivet holes 21 of the strips and body in alinement with each other.

A reinforced receptacle or barrel, comprising a sheet metal body, sheet metal reinforcing strips seated on the external surface of the body, relatively thick metal hoops having rigid anvil portions seated on the internal surface of the body, the inner surfaces of the hoops being exposed within the end portions of the body, said strips, body, and hoops having coinciding orifices, and rivets having relatively large hardened wear-sustaining heads seated on and in binding contact with the outer surfaces of the sheet metal strips, and malleable Shanks inserted in said orifices and upset at their inner ends on said anvil portions to form relatively small inner' heads, in binding contact withand protected by the anvil portions of the hoops.

In testimony whereof I have affixed my signature.
